在文件 includes/lib_goods.php 最后加上
//*** 调用商品分类指定分类下级分类
function get_parent_id_tree($parent_id)
{
$three_c_arr = array();
$sql = 'SELECT count(*) FROM ' . $GLOBALS['ecs']->table('category') . " WHERE parent_id = '$parent_id' AND is_show = 1 ";
if ($GLOBALS['db']->getOne($sql))
{
$child_sql = 'SELECT cat_id, cat_name, parent_id, is_show ' .
'FROM ' . $GLOBALS['ecs']->table('category') .
"WHERE parent_id = '$parent_id' AND is_show = 1 ORDER BY sort_order ASC, cat_id ASC";
$res = $GLOBALS['db']->getAll($child_sql);
foreach ($res AS $row)
{
if ($row['is_show'])
$three_c_arr[$row['cat_id']]['id'] = $row['cat_id'];
$three_c_arr[$row['cat_id']]['name'] = $row['cat_name'];
$three_c_arr[$row['cat_id']]['url'] = build_uri('category', array('cid' => $row['cat_id']), $row['cat_name']);
}
}
return $three_c_arr;
}
如图：
声明后用$smarty调用，就是在index.php中加上下面一句：
$smarty->assign('get_parent_id16_tree', get_parent_id_tree(16));//调用父级分类6的下级分类
最后就可以在index.dwt模板文件里开始调用了

呵呵，这样就解决了，希望对你有用处 |
